Answer:
1. As rocket mass increases, acceleration decreases.
2. The inverse of the mass of the boat.
Explanation:
1. Newton's second law of motion states;
F = ma
where F is the force applied, m is the mass and a is the acceleration.
Therefore, increasing the mass of a rocket increases its weight which would reduce its acceleration provided that the force is constant. Thus, as rocket mass increases, acceleration decreases.
2. The slope of the graph can be expressed as;
From Newton's second law,
F = ma
Slope = (Δa) ÷ (ΔF)
Slope =
⇒ =
Therefore, the slope of the graph is the reciprocal of the mass of the boat.
375km
Explanation:
Given parameters:
Time of travel = 5hr
Average velocity = 75km/hr south
Unknown:
Displacement between Chihuahua and El paso = ?
Solution:
Velocity is the rate of change of displacement of a body with time. It is a vector quantity that has both magnitude and direction;
Velocity =
Since the unknown is displacement;
displacement = velocity x time
input the values;
displacement = 75km/hr x 5hr = 375km
